  • Description

    Megger TPT320 AC/DC Voltage Tester

    This product is also available in a safe isolation kit alongside the Megger MPU690 Proving Unit for just £89.00! Click here to find out more.

    Offering AC / DC voltage measurement from 12 to 690 volts alongside continuity and phase rotation testing, the Megger TPT320 Voltage Tester gives electricians and electrical engineers a truly versatile instrument.

    Presenting voltage readings by both LCD and LED display, the TPT320 provides continuity measurement from 0 to 500kΩ whilst also signalling continuity and voltage measurements above the threshold with an acoustic sounder.

    User-friendly and time-efficient, the Megger TPT320 makes phase rotation simple, avoiding the crossing of test probes sometimes adopted by 2-pole testers. It also ensures that RCD, RCBO and Safety Breakers are not tripped when conducting tests between phase and earth on a circuit, saving time and hassle when working.

    The TPT320 in CAT IV 600V rated with an IP64-rated body and has a range of safety features including an LED torch for safe use in low-lit environments and a function that warns of dangerous test voltages even when batteries are exhausted. The GS38 tips are also provided with protective shrouds as standard.
